FIRELESS STOVE.

Application led February 19, 1920. Serial No. 359,828.

T 0 all whom it may concern:

Be it known that I, GEORGE A. TAYLOR, citizen of the United States,residing at Muncie, in the county of Delaware andState of Indiana, haveinvented certain new and useful Improvements in Fireless Stoves, ofwhich the following isa specification.

This invention relates to improvements in fireless stoves of the typewhich consists of an outer case, and an inner case, with heat insulatingmaterial interposed; the con-'1 tainer so provided being intended tomaintain the temperature of the article placed therein.

To provide a tireless stove by whichy the temperature of the material-splaced therein may be maintained, and in which the actual cooking offoods may be accomplished, are the objects of this invention, and itconsists of the new construction, combination and 'arrangement of partsand the features of improvement, shown in the annexed drawings, anddescribed in the present specification. The invention is defined in theappended claims.

The several parts of the invention are identified by suitable charactersof reference applied thereto in the different views in the drawings, inwhich- Figure l is a perspective view of one of my improved tirelessstoves, the two-well size.`

Figure 2 is a frontal view, portions thereof being broken away and oneend of the device being shown in central longitudinal section.

Figure 3 is an end view of Figure l, the lid or closure plate of thestove beingat closed position. y

Figure Il is a top plan view of the stove, a portion on the top plate,and of the cover lids being broken away.

Figure 5 is an enlarged detail view of the vent device.

Figure 6 is a transverse vertical sectional view of the lid.

My present invention is embodied in the preferred form and constructionshown. In the model illustrated, namely-the two well size, the body maybe thirty inches in length, fourteen inches wide, and fifteen inches inheight. This box shaped body comprises a sheet metal wall plate havingthe side portions A, A, and the end portions B and B. The top `plate Cmade of sheet metel, preferably aluminum, and provided with circularopenings, has its edges secured to the top edges of the side plates A,A, and the end plates Band B. O designates the bottom plate. Each of thecylindrical wells D, made of sheet metal, preferably aluminum, has itsyrim secured. to the edge of the circular opening in the top plate C.,Adapt-` ed to reside immediately in contact with the bottom lof the`well D is a sheet metal disk E. This disk may be made of steel or othermetal and its function isto form a reinforcement for the bottom ofthelwell cylinder. To avoid electro-chemical activity between the twometals, this disk is subjected to a coating of asphaltum or otherelectrical insulating compound.

The frame for the aforesaid sheet metal body consists of a combinationof wooden strips F, G, and H, suitably connected together and adaptedto(` brace and stien the sheet metal sides A and the end plates B.

In completing the assembly of the several parts constituting my improvedtireless stove, the structure just described, is disposed at invertedposition on the workers bench; cylindrical sleeves K of sheet metal arethen disposed at position, the` rimsK1 of same being disposed at contactwith the underside of the top plate C. The sheet metal disks Earedisposed at place in contact kwith the bottoms of the well cylindersD and D. It will be observed that the diameter of the sleeve K issufliciently greater. than that of the well cylinder D that the space Iis provided, and in which the non-A circulating air so contained, is theinsulating medium. Additional insulation between the sleeve K and thewall plates, consists. of-a wrapping L made of a succession of layers ofcorrugated or cellular paper or composition, and which wrapping fillsthe space between the sleeves K and the wall plates, and being retentiveof the air, constitutes effective insulation for the well cylinders. Itis contemplated that cellular tissue of other material may be used, theobject being to have an air space therein partitioned in such mannerthat any circulation of the airso confined, is prevented, and such airconstitutes the main medium ofinsulation. The corner spaces of the bodyare then packed tightly with eXcelsior Mor other suitable resilientlight packing material.

Immediately at contact with the disk E is placed a filling of fireproofmaterial such as mineral wool N, and it insures proper insulindricalcontainer inside and of diameter less than that of the tubular sleeveand having its upper rim opening through the said top plate, and aclosure plate for the said opening.

2. A tireless stove, comprising a box shaped body, a top plate, an opensleeve extending from the bottom of the body to the top plate of thebody, a metal plate to tit in and slightly above the bottom of the saidsleeve, ireproo insulation between the said plate and the bottom plateof the body, heat insulating material surrounding the said sleeve, acontainer inside said sleeve and having its upper end opening throughthe top plate, said container being of a diameter less than the diameterof said sleeve and to'provide an air space between the container and thesleeve, and a closure lid for said container.

3. A iireless stove, comprising a box shaped body, a top plate, atubular sleeve extended upwardly from the bottom plate to theundersurface of the top plate, the lower end of the sleeve being coneshaped, a sheet metal disk electrically insulated and of diameter to bewedged into tightened osition in the coneshaped portion of the tu Eularsleeve and slightly above the bottom of the tubular sleeve, a containerof diameter less than that of the tubular sleeve, lireproof materialbetween the disk and the bottom plate of-the body, layers of cellularinsulating material between the sleeve and the walls 1 of the body, andpacking between the cellular insulating material and the walls of thebody.

4. A lireless stove, comprising a box shaped body, a top plate, an opensleeve extending from the bottom plate to the underside of the top plateoit' the body, a metal plate to fit in and slightly above t-he bottom ofthe said sleeve, ireproof insulation between the said metal plate andthe bottom plate of the body, heat insulating material surrounding thesaid sleeve, a container inside said sleeve and having its upper endopening through the top plate, `said container being of diameter lessthan the di-` ameter of the said sleeve and to provide a f `a closurelid of hollow construction and hav-` ing a resilient bottom plate,stalling for the interior of the lid to maintain the bottom plate of thelid at normally bul ged position, and a clamping means to draw the lidto tightened engagement with. the top plate of the box so that thesurface of the said top plate immediately surrounding the rim or mouthof the containeris sealed.

In testimony whereof I aliix my signature in the presence of twowitnesses.
